It has been observed-that in the construction of containers such as collapsible tubes for the reception of tooth paste, pharmaceutical preparations, cosmetics and the like which are now in general use and on the market, an exteriorly' threaded delivery neck is provided and. the delivery openingtherethrough isclosed by means of-a removable threaded cap. Use of such a cap is objectionable for the reason that the same is often misplaced or dropped and lost in the waste pipe of a wash basin.

it is therefore one of the principal objects of the present invention to improve the construction or" the delivery end of a container of this character by providing a closure which forms apermanent part of the delivery end of the container.

Another object of the invention is to pro-' vide a closure for the delivery openingwhich is provided with means adapted to co-act with the container neck to position and retain the closure in sealed contact with the neck when the closure is disposed over the delivery 0 ening.

A-fllZt- HGE o ject of the invention is to provide a closure which may be manufactured as a separate element. the same being so constructed as to permit of a ready assembly of the same with the neck.

A still further object of the invention is to provide a device of the character described which is simple in construction, cilicient in purpose and inexpensive to manufacture.

With these and other objects in view which will be more apparent as the nature, purpose and operation of the device is better understood from the following description and claims reference is made to the ac companying drawings forming a part of this application and in which Figure 1 is a perspectiveview of the container with the improved construction of the delivery end clearly illustrated as as sociated therewith.

Fig. 2 is a fragmentary enlarged detail view of the delivery end.

Fig. 3 is an end view of the same.

Fig. i is a vertical sectional view there through taken on the line 4-4 of Fig. 2.

Referring to the drawings by characters of reference which denote like parts throughout the several views thereof 10 designates the container body and 11 the delivery end which is provided with a substantial'ly rectangular oblong neck 12 having a delivery opening 13 therethrough disposed ai one side of the horizontal center thereof. The upper surface of the neck 12 is provided with a horizontal flat portion 14 disposed toward the same side of the" neck through which the delivery opening extends. Trunnions 15 project outwardly from the long sides of the neck 12, substantially in alinement with the deliveryopening 13 and an arcua'te portion 15 is provided on the upper surface of the neck concentric with the axis of the trunnions 15. One extremity of said arcuate portion merges into the fiat por-.

tion 14 and the opposite extremity intersects the vertical end wall 16. The closure member comprises a head 17 having spaced depending parallel legs 18 formed integral therewith, the lower extremity of said legs being formed to provide hookedterminals '19 which receive the trunnions L5 in order to swingingly associate the closure member with the neck 12. The underside of the head is recessed as'at 20 for the reception of a resilient gasket 21 which is designed to contact with the upper surface of the neck to normally exert pressure between the head and the upper surface. A bendable pin 22 is' formed on the end wall 16 adjacent one oi. the side walls. the length of said pin being such as to dispose its free extremity within the radial path of "movement; ofthe outer surface of the gasket when the closure member is swung upon its pivot. This permits of the easy application of the closure to the neck in assembling the same. After the closure member has been applied and swung upon its pivot to position the outer surface of the gasket in contact with the upper surface of the neck, the pin 22 is bent around the corner of the neck to dispose said pin along the side of the same in order to prevent the removal of the closure mem her from the neck.

In order to provide means to retain the gasket in sealing contact with the neck over the delivery opening. the legs 18 are cut away as at 23 and said cut away portions are each provided with a depression 24. Bosses 25 are formed on the side faces of the neck and the same are provided with lugs 26, which are adapted to receive the depressions 24 for co acting engagement therewith to prevent casual swinging movement of the closure member. The interengagement of the depression 24; with the lugs 26 is effected by the inherent quality of the resilient gasket which tends to maintain the co-acting engagement and relation of the depressions with said lugs. The formation of the hooked terminals 19 of the legs serves to permit of sliding movement of the closure on the trun- Mom. The arcuatc surface 15 is provided with an enlargement 27 which is designed to co-act with the gasket to retain the closure member in an open position.

The operation is as follows: to open the closure member for gaining access to the intel'ior of the container, it is only necessary to exert a slight downward pressure on the head 17, at the same time forcing the same toward the enlargement 27, the downward movement of the closure member serving to disen age the depressions 24 from the lugs 26. a s the gasket comes in contact with the enlargement 27, a frictional binding between the two will be effected and serve to retain the closure member in an open position. Should the closure member be ad uniced far enough to pass the enlargement 27. one of the legs 18 will contact with the pin 22, thereby preventing the separation or possible loss of the closure member. \Vhen the closure member is swung, to a position to close and seal the delivery opening. the head is forced slightly downward against the inherent resiliency of the gasket until the depressions 24 engage over the lugs 26, the expansion of the gasket serving to lock the depressions over the lugs. If for any reason it sllmlld be found necessary to remove the closure member entirely from the neck 12. it is only necessary to bend the pin :22 to project it at right angle with respect to the wall 16. The closure member is then free to be swung to a horizontal position from which position the hook t 11 (llsfiilg'uged f th i nals 19 may be I'Ptll trunnions 15.

While there has been illustrated and de scribed a single and preferred form of the invention, it is understood that the same is merely illust'ative of one embodiment of the same and variations and changes in the details of construction which fall within the scopeof the claims, may be resorted to when found expedient.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a container neck having a delivery opening therethrough, a closure therefor having a detachable sliding pivotal connection therewith. means formed respectively on the closure and the neck adapted to co act with each other to position and retain the closure in sealed contact with the neck over the delivery opening and a bendable pin carried by the neck adapted to be respectively bent to positions for limiting or permitting the free swinging movement of the closurein one direction.

2. In a container neck having a delivery opening therethrough. a closure therefor having detachable sliding pivotal connection therewith. bendable means adapted to be bent to positions for preventing entire detachment of said closure from the container, means formed respectively on the closure and the neck adapted to co-act with each other to position and retain the closure in sealed contact with the neck over the delivery openin and means on the neck adapted to co-act with the closure for retaining the same in an o en position.
